PAT A 1004. Counting Leaves (30)【vector+dfs】
题目链接:https://www.patest.cn/contests/pat-a-practise/1004
大意:输出按层次输出每层无孩子结点的个数
思路:vector存储结点,dfs遍历
#include<iostream>
#include<cstdio>
#include<string>
#include<vector>
#include<algorithm>
using namespace std;
const int maxn=1e2+;
int n,m,k,x,f[maxn],deep,y;
vector<int> t[maxn];
void init()
{
cin>>n>>m;
while(m--)
{
cin>>x>>k;
while(k--)
{
cin>>y;
t[x].push_back(y);
}
}
}
void dfs(int x,int dep)
{
deep=max(dep,deep);
if(t[x].size()==)f[dep]++;
for(int i=;i<t[x].size();i++)
dfs(t[x][i],dep+);
} int main()
{
init();
dfs(,);
for(int i=;i<=deep;i++)
printf("%s%d",i?" ":"",f[i]);
printf("\n");
return ;
}
